SPECIFICATION forming part of Letters Patent No. 339,677, dated April 13,1886.

Application filed July 21, 1885. Serial No. 172,223.

To all whom it nut z concern.-

Be it known that I, MARTIN SANFORD hIIL- LARD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Windows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of alongitudinal vertical section. Fig. 2 is a vertical section taken on the line a: m, Fig. 1. Fig. 8 is a horizontal section taken on the line y Fig. 11.. Fig. 4 is a vertical section showing windows on a slant. Figs. 5, 6, 9 are detail views. Fig. 7 is a sectional view of a modification, and Fig. 8 is a perspective VIEW.

This invention relates to windows; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and particularly pointed outin the claims.

Referring by letter to the accompanying drawings, A desi nates the window-frame, which is provided with hollow sides A A and a hollow top, A. The hollow top A is provided in its under face with an opening, D, which is closed by a removable piece or door, B. Through this top the cords G0 are introduced to run over the double pulleys D D and the single pulleys D D", located near opposite ends within the hollow top A", a single pulley and a double pulley being provided near each end of said hollow top A, the two single pulleys I) I) being opposite the two double pulleys D D, and being located also a little forward of and to one side of the double pulleys.

The base-piece of the hollow top A is provided on each side of and near the double pulleys D with holes for the passage of the cord 0 G. In the outer faces of the vertical rails of both the upper and lower sashes are pro vided grooves G G, which extend the full length of said side rails. The smaller grooves,

(No model.)

G, are semicircular in crosssection, and are made in thelongitudinal middle of the rectangular grooves G, and extend the entire length of the vertical sash rails. In the smaller 55 semicircular grooves,G, rubber tubes H,with wire cores H, are secured by staples H".

To the vertical edges of both the upper and lower sashes are secured the pivoted sliding strips I I. These pivoted sliding strips I I are rounded or beaded on their inner or abutting edges, so that when the sashes are tilted or turned on their pivots to incline them or place them at any desired angle to the sliding strips the sliding strips will not out or wear the rubber tubing, the latter being expanded by pressure into the larger rectangular grooves,G, in the sides of their sashes. Near their upper and lower ends the pivoted sliding strips are provided with headed threaded friction bolts or studs J, having each a nick in the point of the shank, which latter is untapered and is threaded, so that said frictionbolts can be adjusted by using a screwdriver to compensate for wear and shrinkage, and thus prolong the usefulness of the sliding strips. The sliding strips I I are pivoted to the vertical side rails of the sashes by ratchetbolts K K, the threaded ends of which work in threaded plates or bosses L.

Ratchet-bolts K K are passed through metal seats h M, let into the inner faces of the vertical sash rails of both sashes at about the middle of their lengths, these metal seats being also secured in place by wood-screws. The inner ends of these ratchet-bolts K K are provided with milled or roughened heads M and inside of the heads a distance a little greater than the thickness of the ratchet-levers ll 3 the stems of said ratchet-bolts are provided with rectangular portions or integral wrenches M when the force to be overcome in turning said ratchet-bolts is too great for the thumb and finger.

Guard strips are provided between the sashes, and the usual guard-strips are provided at the inner and outer sides of the sashes. These, however, do not project far enough from the window-frame to interfere with the tilting of the sashes, and only serve to exclude wind, cold, heat, rain, and dust when the windows are closed.

I am-aware that it is not new to groove the outer sides of the vertical rails of sashes, and arrange tubular gum strips therein, and therefore do not claim such devices broadly; but,

Having described this invention, what I claim, and. desire to secure by Letters Patent, 1s

1. The combination,with the windowframe having the hollow sides and the hollow top provided with two single pulleys and two double pulleys, of the window-sashes having the vertical double grooves in their vertical side Walls, the wire-cored flexible tubes secured in said double grooves, the cords O O, secured to the pivoted sliding strips, and the weights upon the cordsC O, substantially as specified.

2. The combination, with a window sash having double grooves in its vertical side rails, of the rubber tubing, with Wire cores and stapics for securing said tubing in the double grooves, substantially as specified.

3. The combination, with a window-sash and pivoted sliding strip, of the ratchet-bolt having the milled head and rectangular portion on the stem near the head, and a ratchetlever for turning said ratchet-bolt in a threaded seat in the sash, substantially as specified.

4. The combination, with the window-sash and pivoted sliding strip, of the threaded headed friction-bolt having the nick in the point of the threaded stem, substantially as specified.

5. The combination, with the window-sash having the vertical double grooves in the outer edges of its side rails, of the wire-cored rubber tubes in said grooves, and the pivoted sliding strips having beaded inner edges, substantially as specified.

6. The combination, with the window-sash having the vertical double grooves in :the outer edges of its side rails, of the wire-cored rubber tubes in said grooves, the pivoted sliding strip with beaded inner edges, and the ratchet-bolts with milled heads and integral nuts, and the sliding ratchet-levers on said ratchet-bolts, substantially as specified.

7. The combination, with the window-sash having longitudinal double grooves in its side rails, the Wire-cored rubber tubes, and the securingstaples for holding said tubes in the double grooves, substantially as specified.

8. The combination,with a windowsash and the outer sliding bars, of the adjustable pivot and ratchet bolt connecting and clamping the sash and sliding bars, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
